Abstract

A novel redox-induced shape-memory polymer (SMP) is prepared by crosslinking β-cyclodextrin modified chitosan (β-CD-CS) and ferrocene modified branched ethylene imine polymer (Fc-PEI). The resulting β-CD-CS/Fc-PEI contains two crosslinks: reversible redox-sensitive β-CD-Fc inclusion complexes serving as reversible phases, and covalent crosslinks serving as fixing phases. It is shown that this material can be processed into temporary shapes as needed in the reduced state and recovers its initial shape after oxidation. The recovery ratio and the fixity ratio are both above 70%. Furthermore, after entrapping glucose oxidase (GOD) in the system, the material shows a shape memory effect in response to glucose. The recovery ratio and the fixity ratio are also above 70%.

Claims the paper makes

We couldn’t retrieve this paper’s full text, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Chemo-responsive SMPs (pH-, redox-, moisture- and solvent-induced) are one of the barely studied systems in the literature.

    “Chemo-responsive SMPs, pH-, redox- and moisture- and solvent-induced, are one of the barely studied systems in the literature [57-59].”
  • Entrapping glucose oxidase enzyme in β-CD-CS/Fc-PEI hydrogel by casting technique made the system glucose-responsive.

    “Entrapping glucose oxidase enzyme (GOD) in b -CD-CS/Fc-PEI hydrogel by casting technique, made the system glucose-responsive as well.”
  • The original shape could be recovered in 48 h by direct immersion of the sample in glucose solution, where glucose oxidation by GOD led to hydrogen peroxide, the oxidant for recovery.

    “Therefore, the original shape could be recovered in 48 h by direct immersion of the sample in glucose solution (glucose oxidation by GOD led to the formation of hydrogen peroxide, which was the oxidant for the recovery step process).”
  • Immersion of a plane strip in an oxidative solution allowed sample softening as a consequence of complexes dissociation; consecutive immersion of the bended shape film in reductive solution led to fixation of temporary shape (74%), while a second oxidation led to 78% recovery shape.

    “Immersion of a plane strip in an oxidative solution, allowed the sample softening as a consequence of the complexes dissociation. Consecutive immersion of the bended shape film in the reductive solution, led to an acceptable fixation of the temporary shape (74%), while a second oxidation led to a 78% of the recovery shape.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
